Answer 1

As can be seen in the above graph:

(a) g(x) > 0 in the interval: (-4, -2) U (0, 2)

(b) g(x) < 0 in the interval: (-2, 0)

(c) g(x) = 0 at the next x-values: -4, -2, 0, 2

Graphically, the derivative of a function evaluated at a point is seen as the slope of the tangent line that passes through that point of the function.

Then, if the slope is positive, the derivative is positive, if the slope is zero (a horizontal line), the derivative is zero, and if the slope is negative, the derivative is negative.

In the next graph, we can see some of these slopes:

Therefore, the intervals where g'(x) is positive, negative or zero are:

(d) g'(x) > 0 in the interval: (-4, -3) U (-1, 1)

(e) g'(x) < 0 in the interval: (-3, -1) U (1, 2)

(f) g'(x) = 0 at the next x-values: -3, -1, 1

Victor normally sells roadside cashews for $12 per pound and his roadside stands today is discounting the price 25% if Carla buys 2 3/4 pounds of roasted cashews at the Discounted price how much will she pay

Answers

Victor sells roadside cashews for $12 per pound.

Today, the price is discounted by 25%. The discount is

25% of $12 = 25/100*$12 = $3

Thus the discounted price is $12 - $3 = $9 per pound

Carla buys 2 3/4 pounds of roasted cashews at that discounted price, thus she will pay:

$9 * 2 3/4

Expressing 2 3/4 as a single fraction:

2 3/4 = 2 + 3/4 = (8+3)/4 = 11/4

Carla will pay:

$9 * 11/4 = $24.75

Carla will pay $24.75

Concept

In probability theory, the central limit theorem establishes that, in many situations, when independent random variables are summed up, their properly normalized sum tends toward a normal distribution even if the original variables themselves are not normally distributed.

Given:

period of record = 5 years

mean daily revenue = $5400

Standard deviation = $54

We want to identify which of the options perfectly describes the sampling distribution of the sample mean supposing that 36 days are randomly selected.

Using the central limit theorem, we know that regardless of the distribution one samples from if the population mean and standard deviation are:

[tex]\begin{gathered} population\text{ mean (}\mu) \\ \text{Standard devaition (}\sigma) \end{gathered}[/tex]

then, the mean is approximately normally distributed and has a value equal to the population mean, while the standard deviation of the sample means is:

[tex]\frac{\sigma}{\sqrt[]{n}}[/tex]

Hence the standard deviation of the sample means is:

[tex]\begin{gathered} =\text{ }\frac{54}{\sqrt[]{36}} \\ =\text{ \$9} \end{gathered}[/tex]

We can conclude that the distribution is normal with a mean of $5400 and a standard deviation of $9

Answers

To determine if a system of equation have solution you have to determine if the slope (m) is equal or diferent.

If the slope is the same it has NO solution

If the slope is different has a solution

If the equations are equivalents have infinite solutions

To determine the slope the equation must be is the form:

[tex]y=mx+b[/tex]

Then

A.

y = 5 – 3x

In this equation the slope is m = -3

y = -3x + 4

In this equation the slope is m= - 3

The system has NO solution

B.

y = 4x – 1

m= 4

4y = 16x – 4

You need to simplify the equation, as follow:

[tex]\frac{4}{4}y=\frac{16}{4}x-\frac{4}{4}[/tex][tex]y=4x-1[/tex]

Then the equation are the same it means the system has infinited solutions.

C.

5x – 2y = 3

[tex]-2y=3-5x[/tex][tex]y=-\frac{3}{2}+\frac{5}{2}x[/tex]

m= 5/2

10x – 4y = 6

[tex]-4y=6-10x[/tex][tex]y=-\frac{6}{4}+\frac{10}{4}x[/tex]

Simplify:

[tex]y=-\frac{3}{2}+\frac{5}{2}x[/tex]

Then the equation are the same it means the system has infinited solutions.

D.

3x + 7y = 42

[tex]7y=42-3x[/tex][tex]y=\frac{42}{7}-\frac{3}{7}x[/tex][tex]y=6-\frac{3}{7}x[/tex]

m= -3/7

6x + 14 y = 50

[tex]14y=50-6x[/tex][tex]y=\frac{50}{14}-\frac{6}{14}x[/tex][tex]y=\frac{25}{7}-\frac{3}{7}x[/tex]

m= -3/7

The system has NO solution

E.

y = 5 + 2x

m= 2

y = 5x + 2​

m= 5

A purse sells for $325. What was the original price of the purse if it is being sold at a 1625% markup?

Answers

You have that the price of a purse is $325 with a 16.25% markup.

In order to determine what was the original price of the purse, you consider that the original price minus 16.25% of the unknown original price x is equal to 325.

Consider that the 16.25% of a quantity is simply the multiplication of (16.25/100) for such a quanity.

Then, you have:

x - (16.25/100)x = 325 "original price minus 16.25% of the original price"

calculate the quotient left side:

x - 0.1625x = 325

simplify like terms left side:

0.8375x = 325

divide by 0.8375 both sides:

x = 325/0.8375

x = 388.05

Hence, the original price of the purse was $388.05

Find-:

The inverse of a function.

Explanation-:

(a)

For the inverse of a function, x change as y and y change as x and solve for 'y'

[tex]\begin{gathered} f(x)=13x+2 \\ \\ f(y)=13y+2 \\ \\ x\rightarrow y \\ \\ y\rightarrow x \\ \\ \end{gathered}[/tex]

Then solve,

[tex]\begin{gathered} y=13x+2 \\ \\ y-2=13x \\ \\ x=\frac{y-2}{13} \end{gathered}[/tex]

So, value,

[tex]f^{-1}(y)=\frac{y-2}{13}[/tex]

(b)

[tex]g(x)=3x^2-13[/tex]

So, the value is:

[tex]g(y)=3y^2-13[/tex]

The inverse of a function is:

[tex]\begin{gathered} x=3y^2-13 \\ \\ x\rightarrow y \\ \\ y\rightarrow x \\ \\ y=3x^2-13 \\ \\ 3x^2=y+13 \\ \\ x^2=\frac{y+13}{3} \\ \\ x=\sqrt{\frac{y+13}{3}} \end{gathered}[/tex]

So, the inverse value is:

[tex]g^{-1}(y)=\sqrt{\frac{y+13}{3}}[/tex]

(c)

[tex]h(x)=\frac{13}{x+13}[/tex]

Value of h(y) is:

[tex]h(y)=\frac{13}{y+13}[/tex]

Then solve for inverse function,

[tex]\begin{gathered} x=\frac{13}{y+13} \\ \\ x\rightarrow y \\ \\ y\rightarrow x \\ \\ y=\frac{13}{x+13} \\ \\ y(x+13)=13 \\ \\ x+13=\frac{13}{y} \\ \\ x=\frac{13}{y}-13 \end{gathered}[/tex]

So, inverse value is:

Answers

From the given problem, the figure shows the graph of f(x).

Note that translating the graph in a manner of :

[tex]f(x)+c[/tex]

will shift the graph c units upward if the sign is positive or c units downward if the sign is negative.

We are looking for the graph of f(x) - 3

Since the sign is negative, we will shift the grahp 3 units downward, the graph will be like this.

As you can see, the orginal graph intersects at the origin (0, 0). The new graph intersects at (0, -3) since we moved or shifted the graph 3 units downward.

Additional :

If f(x) is translated in a manner of f(x+c), the graph will be shifted c units to the left if c is positive and will be shifted c units to the right if c is negative.

If f(x) is transformed in a manner of -f(x), the graph will reflect over the x-axis.

If the original point is (x, y). It will become (x, -y)

The diagram of the triangle formed is shown below

The length is BC and the width is AB

To find BC, we would apply the cosine trigonometric ratio which is expressed as

Cos# = adjacent side /hypotenuse

hypotenuse = AC = 30

adjacent side = BC

# = 30

Thus, we have

[tex]\begin{gathered} \text{Cos}30\text{ = }\frac{BC}{30} \\ \text{Note, Cos30 = }\frac{\sqrt[]{3}}{2} \\ We\text{ have} \\ \frac{\sqrt[]{3}}{2}=\text{ }\frac{BC}{30} \\ 2BC\text{ = 30}\sqrt[]{3} \\ BC\text{ = }\frac{30\sqrt[]{3}}{2} \\ BC\text{ = 15}\sqrt[]{3} \end{gathered}[/tex]

To find AB, we would apply the sine trigonometric ratio which is expressed as

Sin# = opposite side /hypotenuse

hypotenuse = AC = 30

opposite side = AB

# = 30

Thus, we have

Sin30 = AB/30

Recall, sin30 = 0.5

Thus,

0.5 = AB/30

AB = 30 * 0,5

AB = 15

Thus, the correct option is B

You deposit $400 in an account that earns simple interest at an annual rate of 5%.

a. Write and graph a function that represents the amount (in dollars) of interest
earned after t years. Interpret the slope of the graph.

b. Is there enough money in the account after 4 years to buy a drum set that costs
$500?

Answers

The answer of the given question based on simple interest is (a) The graph of this function is a straight line with a slope of 20. (b) There is not enough money in the account after 4 years to buy the drum set.

What is Simple interest?

Simple interest is type of interest that is calculated on the principal amount (initial amount) of  loan or investment. It is  fixed percentage of principal, and does not take into account any interest earned or accrued over time.

a. The formula for simple interest is I = Prt, In this case, P = 400 and r = 0.05, so the function for the amount of interest earned after t years is:

I(t) = 400 * 0.05 * t = 20t

To graph this function, we can plot points for different values of t and connect them with a line. For example:

When t = 0, I(t) = 0

When t = 1, I(t) = 20

When t = 2, I(t) = 40

When t = 3, I(t) = 60

When t = 4, I(t) = 80

The graph of this function is a straight line with a slope of 20. The slope represents the rate of change of the interest earned per year. In this case, the slope is positive, which means that the interest earned increases linearly with time.

b. After 4 years, the interest earned is:

I(4) = 20 * 4 = 80

The total amount in account after 4 years will be:

A = P + I = 400 + 80 = 480

Since the cost of the drum set is $500, there is not enough money in the account after 4 years to buy the drum set.

Let the ballbe thrown at a 45° angle with the ground.1. Suppose Nancy is standing a horizontal distance of 10 feet from thebasket at the point (-10, 0), and she shoots a basket from 6 feet in theair with an initial velocity of 22 ft/s.Question 1)C. Will Nancy make the basket? Defend your reasoning.D. Use appropriate tools strategically. Experiment on yourcalculator with different direction angles until the player makes abasket. What angle did you use?

Answers

Answer:

(A): Using the equations of motion, we can determine the answer as follows:

[tex]\begin{gathered} x(t)=x_{\circ}+v_{\circ}cos(\theta)t\rightarrow(1) \\ \\ y(t)=y_{\circ}+v_{\circ}sin(\theta)-\frac{1}{2}gt^2\rightarrow(2) \\ \\ y(x)=xtan(\theta)-\frac{g}{2(v_{\circ})^2cos^2(\theta)}x^2\rightarrow(3) \end{gathered}[/tex]

formula (3) is obtained from (1) and (2), using equation (3) the answer is determined as below:

[tex]\begin{gathered} y(x)=xtan(\theta)-\frac{g}{2(v_{\circ})^2cos^2(\theta)}x^2 \\ \\ v_{\circ}=22\text{ f/s} \\ \\ \theta=45 \\ \\ g=32.1522\text{ f/s} \\ \\ y(x)=xtan(45)-\frac{32.1522}{2\times22^2cos^2(45)}x^2 \\ \\ y(x)=x-\frac{32.1522}{2\times22^2cos^2(45)}x^2 \\ \\ y(x)=x-\frac{32.152,2}{484}x^2 \\ \\ y(x)=x-0.06643x^2 \\ \\ (x,y)\rightarrow\text{ Adjusting the position for the shift gives:} \\ \\ y(x)=[(x+10)-0.06643(x+10)^2]+6\rightarrow(4) \end{gathered}[/tex]

The plot of the (4) reveals the following:

Therefore the answer is no.

(D) Trying a new angle theta = 60 degrees gives the following new answer:

Therefore the answer is:

On the math test last week,Jacob got 85% of the questions correct. How can this be percent be written as a fraction ?

Answers

The number in percent can be expressed as the fraction of 100. So 85% can be expressed as,

[tex]\begin{gathered} \frac{85}{100}=\frac{17\cdot5}{20\cdot5} \\ =\frac{17}{20} \end{gathered}[/tex]

85% is expressed as 17/20 in fraction.

Answer: 17/20

Answer:

85/100 = 17/20

Step-by-step explanation: In general, 85% is 85/100, but we can shorten that to an easier answer like 17/20.

Let f(x)=x^2 and g(x)=x-3. Find (f o g)(-5)

Answers

Solution

Given that

[tex]\begin{gathered} f(x)=x^2 \\ \\ g(x)=x-3 \\ \\ \Rightarrow(f\circ g)(-5)=f(g(-5)) \\ \\ g(-5)=-5-3=-8 \\ \\ \Rightarrow f(g(-5))=f(-8) \\ \\ f(-8)=(-8)^2=64 \\ \\ \Rightarrow(f\circ g)(-5)=64 \end{gathered}[/tex]
